ANTISEPTIC GUARD FOR TELEPHONE-TRANSNHTTERS.

Specification of Letters Patent.

Patented Feb. 12, 1907.

Applicatioii filed A st 12,1905. Serial No. 273,879.

To all whom it may concern: I

Be it known that I, GERHARDT E. GRIMM, a citizen of the United States, residing at Camden, in the county of Camden and State of New Jersey, have invented new and useful Improvements in Antiseptic Guard for Telephone-Transmitters, of which the fol lowing is a specification.

My invention relates to new and useful improvements in guards for the mouthpiece of telephone transmitters, and especially to guards which are adapted to be detachably engaged with the transmitter, and include in this structure an antiseptically-treated film or web which when the guard is in operative position is disposed over the entrance to the transmitter to prevent the accumulation of disease germs in the mouthpiece to the transmitter, as well as to destroy such germs, so as to revent the possible spread of disease.

he primary object of the invention is to provide a guard of the character mentioned which is simple in construction, inexpensive of production, and which will eflectively attain the purposes for which it is devised.

A further object is to provide a guard which will embody in its construction im proved and simplified means for supporting a web of antiseptic material in positio'nlto have a portion thereof disposed across the mouthpiece of the receiver and which will permit said portion to be removed when deemed necessary and replaced by a fresh or new piece.

The invention broadly and generally stated consists in a guard embodying in its structure an apertured device having improved and simplified means to engage the transmitter-mouthpiece to maintain the guard in operative position, the aperture in said guard being closed by a sheet or film of antiseptically-treated material.

T he invention further consists in providing new and simplified means for supporting a roll of the antiseptically-treated material in position to permit portions of the latter to be successively drawn across the opening to the j mouthpiece of the transmitter.

I have fully and clearly illustrated my invention in the accompanying drawings, to be taken as a part of the invention, and where- 1ntour as the plate 1.

Figure 1 is a perspective view of a struc- 1 the plate in position for use.

tion of the guard detached from the transmitter. Fig. 3 is a central vertical section through the guard, and Fig. 4 is a transverse central section thereof.

Referring to the drawings, the referencenumeral 1 designates a plate of any suitable material, preferably cardboard or similar ma-- terial, having the proper degree of rigidity said plate being constructed to be supported across the mouthpiece 2 of the well-known form of telephone-transmitter and being formed with a central opening 3, which registers with the opening in the transmittermouthpiece when said plate is in operative position thereon.

The plate 1, as shown in the drawings, is preferably rectangular and is provided with suitable means for detachably engaging the mouthpiece 2 of the transmitter to support This engaging or attaching means consists of oppositely disposed arms or wings 4 5, which may be formed integral with said plate 1, said wings or arms 4 5 being bent or folded rearwardly on the rear face of said plate with their unattached ends free and extending toward each other, as shown. in placing the complete guard in position on the mouthpiece 2 of the transmitter, as hereinafter described, the ar -ns 4 5 are arranged to engage and grasp the said mouthpiece and serve to trictionally engage the latter at (liametrically opposite points thereon. in order to provide for the more secure and eifective engagement of the wings with the transmitter, the'vertical free edge of each wing is formed with a curved recess 6, in which the mouthpiece is received,

and which curved portions embrace the circular mouthpiece 2 and afford a more satisfactory engagement than were said vertical engaging faces left straight.

Arranged over the front face of the plate 1 and in a substantially parallel plane thereto is a plate 7, having tin opening 8 therethrough so located as to register with the opening 3 in the lirst-nained plate, said plate 7 .being preferably of the same size and con The two plates 1 and 7 are permanently secured to each other, so as to provide a practically integral structure, said plates being so secured on thcir'vertical side edges as to have their inner faces in substantial surface contact. The means for securing the plates together consists'ot' wirestaple fasteners .9 of well-known form, one of which is located at each corner of said plates and closelv adjacent the. vertical edges thereof, the prongs of" said staples being inserted through the plates 1 and 7 and the i wings 4 and 5, so that not only are the said plates firmly secured together, but the wings 4 5, being secured or anchored to the plate 1 Z the lower edge of the 1'iln1 and pulling thereon at a point removed from the r edges, great rigiditv and grasping strength is given to said wings, so that they l orm elastic orspring mouthpiece-engaging clips and hold the guard more etl'ectualtv in position than it the were free to move on the fold b which the. are connected to the plate 1. While I have shown the plates secured b wire staples as at'l'ording simple and ellicient means for this purpose, it is, however, obvious that other means might be emploved, if desired, without departing from the spirit ol m\ invention.

it will be seen that although the rear and front plates 1 and 7 are securetv fastened together a space is atlorded between them through which a lilm ol' antisepticall treated material ma be inserted to take position between said disks or plates to cover the openings 3 and 8 therein in order to intercept the passage oi the breath of the operator when the transmitter is in use and also to prevent access of dust and other foreign substance to the mouthpiece.

in the form ol the invention shown means is provided for supporting a suppl \-roll ol' antiseptically-treated material in position to have port-ions thereof successivel v drawn into position between the front and rear plates over the openings therein. Th s means is constructed as follows: The front plate 7, heretofore described, is formed on one of the edges which is not secured to the plate 1 with an integral extension 0, which is curved over on the back of the plate 1, with its free edge in engagement with said plate, said curved extension forming a cylindrical casing or housing 10, in which a roll 11 of the antiseptic film may be supported, said roll lying with its horizontal longitudinal axis parallel with the upper edge of the plate 1, so that said tilm may be drawn from the roll and passeddown between the plates 1 and 7 over the 0 enings therethrough. It will be seen that t e upper edge of the plate 1 extends up into the s ace between the outer volute of the roll, w rich leads to the plate- 0 enings, and the body of the roll, so that t e film is drawn evenly and smoothly from the roll and the jamming oi' the tilm in the housing is prevented.

In order to revent the roll from being displaced from tie housing through the ends thereof, I form the extension!) at each end of the housing with a tongue 12, which is bent up at right angles to the shell of the housing into position to close the ends of the latter, as clearly shown in Fig. 1 of the drawi It is evident that by the construction until a fresh portion is unrolled from the roll and drawn across the openings, the used portion of the film being torn oil, the lower edges of the plates serving as a cutting edge for the purpose.

llaving thus described my invention, what I claim as new, and desire to secure by Letters Patent, is v 1. in a guard of the character described, a plate having an opening, two of the sides of said plate being parallel and each provided with a rearwardly-directed attaching-wing, and a second apertured plate arranged over said first-named plate and connected thereto at the .sides bearing the wings, said second plate being formed on one of its unattached edges with an extension bent upon itself to form a housing, adapted to receive a roll of antiseptically-treated material in position to have said material pass from the roll between said plates over the openings therein.

2. in a guard of the character described, a plate having an opening, two of the sides of said plate being parallel and each provided with a rearwardlv-directed attaching-wing, a second apertured plate arranged over said first-named plate and connected thereto at the sides bearing the wings, said second plate being formed on one of its unattached edges with an extension bent upon itself to form a housing, a roll of antiseptically-treated material mounted in said housing in position to have said mrterial pass from the rollbetween said plates over the openings therein, and means to prevent displacement of the roll from the housing.

3. in a guard of the character described, a plate having an opening, two of the sides of said plate being parallel and each provided with a rearwardly-directed attaching-wing, a second apertured plate arranged over said first-named plate and connected thereto at the sides bearing the wings, said second plate being formed on one of its unattached edges with an extension bent upon itself to form a' housing, and-a, roll of antiseptically-treated material mounted in said housing in position to have said material pass from the roll between said plates over the openings therein, said extension being formed with tongues bent to close the ends of the housing.
